BICYCLE-SADDLE.

SPECIFICATION forming part of Letters Patent No. 328,863, dated October 20, 1885.

Application filed August 14, 1885. Serial No. 174,410. (No model.)

To aZZ whom it may concern:

Be it known that I, CALVIN T. STARBUOK, of Wilmington, in the county of Clinton and State of Ohio, have invented a new and Improved Adjustable Saddle for Bicycles, of which the following is a full, clear, and exact description.

My invention relates to the construction of an apparatus that will enable a bicycle-rider to adjust the saddle to or from the post; and the invention consists of aseat-supporting carriage mounted on the spring and held in position by a small cord or chain that reachesto a drum that is controlled by a coiled spring and carried in a casing secured to the backbone of the machine.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate cor responding parts in all the figures.

Figure 1 is a side View of a portion of the backbone of a bicycle, showing the saddle as mounted and held by my adjusting attachment. Fig. 2is an interior view of the drum-inclosing casing, showing the spring in section; and Fig. 3 is a eross'sectional view taken on broken line or w of Fig. 2.

Referring now to Fig. 1, A represents the backbone, and B the spring of the bicycle. Upon this spring B the saddle-carriage O is mounted, said carriage being provided with rollers c i, arranged one above and the other below the spring 13 at each end of the carriage. The saddle D is secured to this carriage in any of the well-known ways. A small chain, a, reaches from the carriage C to a drum, E, contained within a case, b, that is secured to the backbone A in front of the point where the spring B is secured thereto. The drum E is loosely mounted on a shaft, d, that extends centrally through the case b. A ratchet-wheel, e, is rigidly affixed to the drum E, and an arbor, f, is secured to the ratchet c, all these parts turning loosely on the shaft d.

A spring, h, is coiled about the arbor f, one end of the spring being secured to the arbor and the other to the case, as shown in Fig. 2, the tendency of the spring being to wind up the chain a, and thereby draw the carriage O, and with it the saddle D, toward the case b. the spring It, I provide a mechanism forholding the drum in any desired position. This mechanism consists of an arm, is, that passes down behind the ratchet e and then extends forward, so that a catch-tooth, Z, which it carries, may be brought into engagement with the ratchet-wheel e. The shank of the arm 70 passes up through the center of a standard, n, formed on top of the case b, and terminates in a knob, m, the under side of which is flat, as shown.

The top of the standard a is beveled ofi to correspond with the cam-face 0 of the locking block 1), through which the shank of the arm 70 passes. This locking-block is provided with a handle, q, so that the block can be easily turned and brought to bear against the under side of the knob m, thereby locking the tooth Z in engagement with the ratchet e, and holding the parts in the desired position, from which they will not be moved by an accidental pressure on knob m.

The spring 8 acts to hold the tooth Z against ratchet 6, but the locking device described prevents all possible chance of the accidental tripping of the parts.

When the rider desires to adjust the saddle toward the drum, he moves the handle g to the position shown in the drawings, and depresses the knob m, thereby releasing the cat ch-tooth Z from engagement with the ratchet e, and allowing the spring h to rotate the drum E and wind up the chain a, thus drawing the saddle and its carriage toward the drum. hen the saddle has reached the proper position, the rider releases the knob m and turns the handle thus locking the parts in place. To move the saddle from the drum, the catch-to0th Z is released in the manner described and the saddle pressed back against the action of the spring.

By the use of such an attachment as I have described the saddle may be moved to any required position upon the spring B; consequently the bicycle maybe more easilymounted, and when going down steep grades or over rough ground the saddle may be moved back, thus preventing the liability of taking a header. Another and a very important advantage is that the backbone may be made longer, thus throwing the forks farther forward, thereby allowing the rider to get higher up on the wheel when ascending steep grades.

Having thus described my invention, what 3. In a bicycle, the combination, with the saddle and its carriage, of a chain, a, drum E, ratchet 6, spring h, and an arm, is, having tooth Z and knob m, and projecting through a standard, n, and cam-faced locking-block 1), substantially as described.
